Physical properties

Formation & geological history

Formed through the flow of mineral-rich water or volcanic ash through mud and cracks. The distinctive 'pictures' are created by high iron content and other mineral oxides that petrify over millions of years, often in volcanic or sedimentary environments.

Uses & applications

Primarily used in jewelry (pendants, beads), cabochons, metaphysical practices, and as decorative ornamental stone.

Geological facts

Picture Jasper is often called a 'hidden message' stone; many believe its patterns represent scenes from the earth's past or landscape 'maps' of ancient civilizations.

Field identification & locations

Identified by its opaque, porcelain-like texture and complex, dendritic or swirling patterns that resemble landscapes. Commonly found in Oregon, USA (the Biggs and Deschutes areas are famous for high-quality specimens).
